Question

At what rate of interest will the simple interest be half of the principal in 5 years?​

Answer 1

Answer:

Let the principal be P

Let the simple interest be S.I= P/2

Let rate of interest be r

t= 5 years

S.I = P x r x t/100

=> P/2= P x r x 5/100

=> R= 10

Hence the rate of interest would be 10%

Step-by-step explanation:

Answer 2

Answer:

10%

Step-by-step explanation:

Let , the principal be x and

SI = x/2

T= 5 years

R= SI× 100/P×T

R= x *100/x * 5 * 2

R= 10%
